Amount of wattage?

[Wilty]

GREAT! Clearly been taking the whole MH thing for granted.

While on the topic has anyone used a light spectimeter (spelling?) to measure the range and parimeters of the lights in their whole system combined?
I was going to borrow one from a friend at work but his son has it. Apparently very expensive when they are more high-tech then the little things we used in high school lol.
